Electric winch for drilling wells
Volec, Martin ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
This bachelor thesis undertakes design of two speed electric winch for the headgear specified for the drilling of the water wells through the use of core technology with the loading capacity up to 1000 kgs. Thesis consists of the theoretical as well as the operational part. Theoretical part is occupied with the possibilities of the problem solving, calculates the main winch parameters. In the study the reasons for choices of the main parts of mechanism e.g. electromotor, transmission, winch and others are given. Generally the brief introduction into the problem is inserted in each chapter prior to the calculations. Operational part involves the drawing of the overall configuration and the cable drum setup.

Stroke mechanism of bridge crane
Tomeš, Jakub ; Sedláček, Martin (referee) ; Škopán, Miroslav (advisor)
The bachelor thesis deals with the design of bridge crane lifting gear for a load not exceeding 10,000 kg. The work includes the design of the basic parts of the lifting gear, such as rope diameter, rope drum and rollers. There is also included the choice of standardized parts such as electric motor, crane gearbox, flexible clutch or drum brake. The last chapter describe the strength calculation of the rope drum and the bearing life calculation together with the design of welds and tight pen. The output of the bachelor thesis is the drawings of the cable drum weld and the mechanism of the lifting mechanism.

Design of the upper beam two columned shelf stacker
Kuděla, Jan ; Kozok, Zbigněv (referee) ; Škopán, Miroslav (advisor)
This master thesis deals with a concept of two columned shelf stacker’s upper beam. The first part contains a research of storage systems used in logistics and a description of the shelf stack’s basic parts. The second part is dedicated to the draft of the pulley arrangement with a rope calculation, pulleys and shafts, in the same the draft of the pulley attachment to the rope leading to the counterweights. It is followed by the concept of the couple winch drive ensues synchronized with the electronic cardan. The final part depicts the dynamic analysis of the lifting truck’s movement in the dependence on the load size and distribution respecting the dynamic effect of the counterweight act.

Shelf stacker for storing pallets in an automatic store
Javůrek, František ; Kozok, Zbigněv (referee) ; Pokorný, Přemysl (advisor)
Target of the submitted work was a proposal of a new type of shelf stackers in the range from 8 to 36 m that are working in fully automated warehouses. By using a fully automated storage system all human supervision in ordering pallets in a warehouse are canceled and everything is taken over by the control system. These stores are very efficient and save both time and money. With regard to safety requirements, regular inspections should be provided to the system. At the beginning of this work, there was done a short introduction to the particular study including the description of basic parts of the shelf stackers. Consequently, there were done relevant computations for the drag device and its drive, drives for the travel and the finite method was used to the stress analysis of the mast shelf stacker. In the last part of this thesis is done a safety concept.

Stroke mechanism of bridge crane
Ujčík, Miroslav ; Malášek, Jiří (referee) ; Škopán, Miroslav (advisor)
This thesis deals with the design of a stroke mechanism of the bridge crane with capacity of load 12 000 kg, which will have served as a plant crane with regular use. The first part of this thesis is devoted to the critical research of similar existing solutions, on the bases of which a suitable order of the arrangement is chosen. The other part of the thesis is devoted to the calculation of the main dimensions of the stroke, on the basis of which the individual components are selected, this are hoist elements of the rope system, such as roller, rope and rope drum, in which the fatigue calculation is performed. Another part of the thesis tackles design and parts calculation of the lifting mechanism, such as electric motor, clutch, brake and gearbox. The final part of the thesis is devoted to the calculation and control of the drum flail, bearing and tension calculation of the parallel key. Constituent part of this thesis is also drawings´ documentation, which enclosed drawing of the lifting mechanism assembly and the welding subassembly as well.
